Hadoop守护进程没有停止(Hadoop Daemons not stopping)

 扩展接口ICompletionProposalExtension6支持样式化显示字符串。 它唯一的方法getStyledDisplayString()必须返回一个用于显示的StyledString 。 
 
 您不必创建CompletionProposal实例，而是必须实现自己的ICompletionProposal ，它也实现了上述扩展。 例如： 
 
class StyledCompletionProposal 
    implements ICompletionProposal, ICompletionProposalExtension6 
{

  ...

  @Override
  public StyledString getStyledDisplayString() {
    return new StyledString("test").append(" [10%]", Styler.QUALIFIER_STYLER);
  }

}
 
 此外，必须将内容助手配置为启用彩色标签 。 对于编辑器，这通常在SourceViewerConfiguration::getContentAssistant ： 
 
ContentAssistant contentAssistant = new ContentAssistant();
contentAssistant.enableColoredLabels(true);

The extension interface ICompletionProposalExtension6 supports styled display strings. Its sole method getStyledDisplayString() must return a StyledString that is used for display.
 
Instead of creating an instance of CompletionProposal you would have to implement your own ICompletionProposal that also implements the above mentioned extension. For example:
 
class StyledCompletionProposal 
    implements ICompletionProposal, ICompletionProposalExtension6 
{

  ...

  @Override
  public StyledString getStyledDisplayString() {
    return new StyledString("test").append(" [10%]", Styler.QUALIFIER_STYLER);
  }

}
 
In addition, the content assistant must be configured to enable coloured labels. For editors, this is usually done in SourceViewerConfiguration::getContentAssistant:
 
ContentAssistant contentAssistant = new ContentAssistant();
contentAssistant.enableColoredLabels(true);
